Yes, the rail is thermite welded to a continuous rail except for insulated

1000ft?

How?

I know one way is they lay the rail across successive flat-cars, and
just drag it off the side (or off the end by driving the train out
from under it).

I image-googled "ribbon rail install" and see they also will drag the
rail up to 8 miles, letting it drag between the installed rails! They
meas. 360deg.F after a 3-mile drag.
